Well, 2K Games has just revealed the PC requirements for its upcoming game Battleborn - where 4K is an afterthought and won't be supported at launch. Neither will off-sized displays.

In a blog post, 2K explained the features on Battleborn, and that it'll include a repeatable story mode, that can be enjoyed on your own or with friends in cooperative mode. Hardcore mode will be available for those who don't like it easy, and there'll also be multiple competitive multiplayer modes. As for the PC requirements:

Gamepads: Not using a keyboard and mouse on a PC? Battleborn supports general gamepads, PS4 and Xbox One controllers, with Steam controller support coming after launch.

4K and Different Displays: There will not be support for either 4K or off-sized displays at launch, though we're actively investigating both.
